Learning Objectives

4.3.1.6 Human defence systems

Content	Key opportunities for skills development
$Students should be able to describe the non-specific defence systems of the human body against pathogens, including: • skin • nose • trachea and bronchi • stomach. Students should be able to explain the role of the immune system in the defence against disease. If a pathogen enters the body the immune system tries to destroy the pathogen. White blood cells help to defend against pathogens by: • phagocytosis • antibody production • antitoxin production.$
